cppfiles.c: Update comments.
* cppfiles.c: Update comments.
(_cpp_read_file): Don't check for NULL filenames any more.
* cppinit.c (cpp_start_read): Don't do canonicalization of
in_fname and out_fname. Use the passed file name exclusively.
(_cpp_handle_options): Don't treat "-" as a command line option,
but as a normal filename.
(_cpp_post_options): Canonicalize in_fname and out_fname.
* cppmain.c (printer_init): Don't check out_fname for NULL.
* c-lex.c (orig_filename): Rename cpp_filename for clarity.
